正确解决方法:

我在我的主根项目中添加了. pretierrc .js文件 和写

module.exports = {
    singleQuote: true
  };

好吧，就像那个家伙(@user2982122)提到的，但不是文件，而是代码->首选项->设置，然后寻找引用，选择更漂亮，并勾选两个框

我在项目文件夹中添加了一个名为。pretierrc的文件。 文件内容:

{
    "singleQuote": true,
    "vetur.format.defaultFormatterOptions": {
        "prettier": {
            "singleQuote": true
        }
    }
}

撰写本文时(2022年6月):

请考虑.editorconfig在最后覆盖所有其他配置，找到该文件(很可能在项目的根目录上)，编辑它并添加以下内容:

[*]
quote_type = single

After struggling with the issue I found a useful tool. If you click on the Prettier word in the right lower corner you will get the Output window opened. In that window once you run formatting (in my case it is Alt + Shift + F) you will see all the configurations which prettier will use to format the document. So, we can clearly see that specifying the prettier in the prettier.singleQuote is wrong. It should just be singleQuote. Hence, having the .prettierrc file in my user root folder with the following contents produced the desired result:

{
    "trailingComma": "none",
    "useEditorConfig": false,
    "singleQuote": true
}

此外，请确保已安装了Prettier扩展。

对于JSX使用:

{"jsxSingleQuote": false}
